Refrigerator compressor does not work on 12v DC power, but works on AC power
I have a replacement Norcold DE 105 refrigerator in my 2021 Entegra Ethos. The first refrigerator stopped working on the very first day. It is supposed to run on AC or DC power, and is not powered by propane.
a. It runs fine on AC power but the compressor will not run on DC power.
When plugged into shore power, the refrigerator works
When driving, the refrigerator works
On generator power, the refrigerator works
b. The compressor will not run on DC power
The light comes on and the fan comes on, but the compressor tries to start and turns off
DC voltage at the plug going into the refrigerator is 12.4 volts (measured with a volt meter). The refrigerator isnít supposed to stop running until it falls to 10.4 volts.
The AC outlet the refrigerator is plugged into is not powered on when using the inverter. Iím not sure this is a problem, but it means that I canít use the inverter to power the refrigerator.
All fuses look good, including the 15amp inline fuse on the DC power input line.
Iíve charged the two 105Ah AGM batteries using both solar and shore power. I charged with shore power for 36 hours straight before my last tests.
Do you have any suggestions on troubleshooting?
